Question

Всякий раз, когда я запускаю команду homebrew, я получаю следующие предупреждения, которые я хотел бы исправить:

Ignoring RedCloth-4.2.9 because its extensions are not built. Try: gem pristine RedCloth --version 4.2.9
Ignoring commonmarker-0.17.9 because its extensions are not built. Try: gem pristine commonmarker --version 0.17.9
Ignoring RedCloth-4.2.9 because its extensions are not built. Try: gem pristine RedCloth --version 4.2.9
Ignoring commonmarker-0.17.9 because its extensions are not built. Try: gem pristine commonmarker --version 0.17.9

Запуск gem pristine RedCloth --version 4.2.9 дает следующее:

ERROR:  While executing gem ... (Gem::Exception)
    Failed to find gems ["RedCloth"] = 4.2.9

Я исследовал gem:
